About the Airtac ACE Compact Cylinder ACE32X20B
This AirTAC ACE32X20B is a double acting compact cylinder that extends and retracts its rod with air pressure, delivering a 402.1 N push force at 0.5 MPa and a 345.6 N pull force. The 32 mm bore version uses a 12 mm hard-chrome plated S45C steel rod and a 1/8" port, with a fixed TPU bumper at each end to absorb impact.
Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a longer cylinder will not. The male rod thread (B code) allows direct coupling to fixtures, and at 0.5 MPa, a practical vertical lift of about 24.6 kg is achievable with a 2:1 safety margin, making it a solid choice for light automation tasks.

Where the Airtac ACE Compact Cylinder ACE32X20B Is Used
Fixture Clamping
Use in a CNC machine fixture to clamp small parts with a 402.1 N push force at 0.5 MPa, holding components securely during drilling or milling operations.
Label Applicator
Drive a label applicator head on a packaging line, where the 20 mm stroke and compact body fit between conveyor rails to apply labels to boxes or bottles.
Guard Door Actuator
Actuate a small safety guard door on a machine, using the 345.6 N pull force to retract the door and the 402.1 N push to close it, with the short body fitting inside a slim frame.
Is the Airtac ACE Compact Cylinder ACE32X20B the Right Cylinder?
For a smaller footprint with lower force, consider the ACE25X20 with a 245.4 N push at 0.5 MPa, or step up to the ACE40X20 for a 628.3 N push at the same pressure. This ACE32X20B suits applications needing a compact stroke and moderate thrust, but remember it does not hold position when air is removed; use a rod lock or pilot check valve for load holding.
Since this model has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be used. If you need position sensing, order the ACE32X20SB version. The male rod thread simplifies mounting with rod end accessories, and the ISO 21287 face accepts FA/FB flanges, LB foot brackets, and CA/CB clevis mounts.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACE Compact Cylinder ACE32X20B FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
It follows ISO 21287, a compact standard that saves about 50% of the mounting length of an ISO 15552 profile cylinder. This makes it ideal for tight spaces. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the body is hard-anodized aluminium for durability. Note that the magnet is optional; this version without -S has no magnet, so sensors cannot be mounted.
